Product Description:
The KDA 2.1-150-3-AY0-W1 refers to a KDA Spindle Drive that is manufactured by Bosch Rexroth Indramat a well-known provider of an automation components. It operates with a rated current of 150A and is designed for a DC bus voltage of 300V. The analog speed command value range is ±10V, enabling accurate speed regulation in various machine setups. This drive is designed to manage spindles with great efficiency under severe conditions.
The KDA 2.1-150-3-AY0-W1 Spindle Drive has an auxiliary encoder input that supports both auxiliary and synchronous inputs enabled by its AS 35 interface and analog command configuration. The drive does not include an auxiliary interface which reduces system complexity. It features a forced cooling system using a heatsink blower which ensures effective thermal management during operation. The heatsink supply source requires 220V AC with a frequency range of 50 to 60 Hz. This unit maintains reliable performance within an ambient temperature range of +5 to +45°C and with a maximum permissible temperature of 55°C under reduced nominal conditions. For storage or transport the safe temperature range is -30 to +55°C. Its combination of current rating, encoder support and efficient cooling makes it suitable for a range of motion control systems. The KDA spindle drive may be installed without experiencing any degradation in performance at an altitude of up to 1000 m.
The KDA 2.1-150-3-AY0-W1 Spindle Drive has a humidity tolerance that aligns with class F under DIN 40 040 which confirms durability in controlled industrial environments. This KDA Spindle Drive is designed for precision control and reliable performance in high-speed spindle applications. It meets IP10 protection standards as per DIN 40 050 which makes it suitable for indoor installation with limited ingress protection needs.
